<p><i>Tiffcmp</i> compares the tags and data in two files
created according to the Tagged Image File Format, Revision
6.0. The schemes used for compressing data in each file are
immaterial when data are compared&minus;data are compared on
a scanline-by-scanline basis after decompression. Most
directory tags are checked; notable exceptions are:
<i>GrayResponseCurve</i>, <i>ColorResponseCurve</i>, and
<i>ColorMap</i> tags. Data will not be compared if any of
the <i>BitsPerSample</i>, <i>SamplesPerPixel</i>, or
<i>ImageWidth</i> values are not equal. By default,
<i>tiffcmp</i> will terminate if it encounters any
difference.</p>

<p>Tags that are not recognized by the library are not

<p>The image data of tiled files is not compared, since the

reported for tiled files.</p>
